SPINDLE AN D FLIER FOR SPINNING HEMP, 84.0.

SPECIFICATION forming part of Letters Patent No. 317,118, dated May 5, 1885.

Application filed July 19, 1884. (No model.)

To wZZ whom it may concern:

Be it known that 1, JOHN Goon, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Spindles and Fliers for Spinning Hemp and other Fibrous Materials,'of which the following is a specification.

My invention is more particularly intended for spinning hemp and flax for rope yarn or twine, but may be applicable to the spinning of other fibrous materials.

The invention relates to machines of the Jenny type, wherein are employed closed fliers which have imparted to them a uniform and positive rotary motion, and-spindles which have imparted to them a variable rotary motion, their speed being gradually increased as the size of the bobbins increases in order to preserve a uniform tension in the yarn or twine. Not only is the speed of the spindles increased as the size of the bobbins increases, but the spindles and bobbins require to be driven more powerfully, because the resistance offered by the tension on the yarn to the rotation of the bobbin increases with its size. 1

In order to secure as nearly a uniform tension onthe yarn as possible, the spindle, in a flier of the kind referred to, is commonly driven by a belt through the medium of a slipping driving device, or, as it is more often termed, a drag or a friction-drag. This has commonly consisted of a pulley provided with a friction-face and a friction disk or flange, both mounted on the same shaft, and

one being fast and the other loose thereon;

and the loose member of the friction device is pressed or forced against the positively-rotated member with a variable pressure or force, which increases as the size of the bobbin and the resistance offered to its rotation increase.

An important object of my invention is to dispense entirely with the friction-drag above described, which is always more or less cumbrous and complicated, and therefore expensive.

Although my invention is applicable with advantage to single spindles and fliers, its advantages are more apparent in a machine having a number of spindles and fliers grouped together in a single spindle-stand, and having parallel axes, as shown in my application for Letters Patent filed July 17, 1884, and of which the serial number is 137,907.

The invention consists in the combination, with a spindle and flier and means for driving the flier, of a pulley through which motion is transmitted to the spindle, a driving-pulley for giving motion to the first-named pulley, a slipping, driving-belt encircling or passing around said pulleys, and a tightening-pulley and gearing for producing a varying tension in the slipping driving-belt, and thereby controlling or regulating the degree of slip between the belt aud'the pulley which it drives.

The invention also consists in the combination, with a spindle and flier, means for driving the flier, and a pulley locked to thespin dle, of a driving pulley, a slipping driving belt passingaround'the driving-pulley and the spindle-pulley, and a tightening-pulley tween the belt and the pulley which it drives.

' The invention also consists in the combination, with a spindle-stand, a number or group of parallel spindles and fliers journaled therein, and means for driving the fliers, of pulleys locked to the spindles, a driving-pulley,aslipping' driving-belt passing around or encircling the spindle-pulleys and the driving-pulley, and

a tightening-pulley and gearing for producing a varying tension in said slipping driving-belt,

and thereby controlling or regulating the degree of slip between said belt and the several spindle-pulleys to which it imparts motion,and which rotate synchronously with the spindles.

The invention also consists in novel features in the mechanism whereby tension is applied to thebelt, andiu the combination therewith of a tell-tale or indicator by which the tension of the belt and the degree of fullness of the bobbin or bobbins are indicated also in other combinations of parts,hereinafter described, and

pointed out in the claims.

\ In the accompanying drawings, Figure 1 is a partial side elevation of 'a'machine embodying my invention in which eight parallel spindles and fliers are mounted in a single spindlestand, the spindles being arranged in two verioo tical tiers, four in each tier. Fig. 1* is a detail viewhereinafter described. Fig. 2 is a rear elevation of the machine on a larger scale, the driving-shaft and a portion of the frame only being in section; and Fig. 3 is a partly sectional side view of one of the spindles and fliers on a still larger scale.

Similar letters of reference designate corresponding parts in all the figures.

I will first describe the spindle and flier shown in Fig. 3.

A A designate the two heads of the flier, the former being the driving-head, and A designates longitudinal rods orstretches connecting said heads. The driving-head A has a long tubular journal, a, and the head A has also a journal, a.

B designates the spindle, which has along bearing in the hollow flier-journal a, at one end, and a bearing, a*, in the head A of the flier.

O designates the bobbin, which is nearly as long as the space between the heads of the flier, and which is locked to the spindle B by a bobbincoupling, G. This coupling has a sleeve, 12, which fills the space between the end of the bobbin and the flier, and a radially-projecting arm which has a well-known pin-and-slot connection, b, with the head of the bobbin.

In the coupling 0 is a spring-actuated looking pin or catch, b", whereby the bobbincoupling and bobbin are locked to turn with the spindle, and inasmuch as the bobbin has no lengthwise motion in the flier the said pin or catch serves also to hold the spindle against being withdrawn.

Upon the hollow flier-journal a is secured fast a flier-driving pulley, c, which is here shown as grooved, and on the portion of the journal which projects beyond the flier is a loose pulley, 0, having a long sleeve, 0*. This sleeve is locked fast to the spindle B by lugs or ears and notches c a, or other suitable means.

The hollow journal a at the head A of the flier is journaled in a bushing, d, which is intended to be secured fast in the frame, and on the end of which is a fixed pinion, d. The journal a projects beyond the bush and pinion, and thereon is secured a capstan-head, D, the capstan-barrel, c, of which is rotated by suitable bevel and spur gearing from the fixed pinion d as the capstan-head is revolved about said pinion by the rotation of the flier.

In the end of the capstan-head D is asocket, 6, wherein a nipper is to be secured, as hereinafter described, and the sliver or yarn 3 passes from the capstan-barrel 6 through the hollow journal a, over one or other of two guide-pulleys, s, and thence over one or other of two guide-pulleys, s". The guide-pulleys s s occupy fixed positions on the flier, and from the pulley s the yarn 8 passes lengthwise of the flier and over one or other of two guidepulleys, 8 by which it is directed onto the bobbin 0. The guide-pulleys .9 do not occupy fixed positions on the flier, but constitute traverse-guides, and are mounted on a traveler, E, provided with sockets g, which are fitted to slide along the flier rods or stretchersA.

The traveler E is made in the form of a light ring, having an annular rib or'tongue, 9*, whereby it may engage with a reciprocating head, and by this means the ring or traveler is traversed along the flier, and the desired traverse motion for winding the yarn on the bobbin is secured without any lengthwise movement of the bobbin or flier relatively to each other.

The construction and mode of operation of the spindle and flier, including the traverse motion and the capstan-head D, are fully described in my application for Letters Patent filed July 17, 1884, and of which the serial number is 137 908, and no further description thereof is here necessary.

Referring now to Figs. 1 and 2, F F are the two end frames, which, with suitable longitudinal rails or stretchers, 19*, form the spindle-stand, and in this stand are j ournaled eight spindles and fliers arranged in upper and lower groups of four each, thus making two vertical tiers of spindles, with four in each tier on opposite sides of the machine.

Fig. 1 shows the four spindles on one side of the machine, and in Fig. 2 all the spindles are shown.

The frame F is provided with bearings for the flier-journals a, and in the frame F are secured the bushes d, which form the bearings for thejournals a of the fliers.

G designates the rotary nipper, which is secured in the capstan-head D'of each flier, and G designates a stationary or fixed nipper, which is supported by an arm, f, projecting from the frame F, to act in conjunction with the rotary nipper of each spindle and flier.

In Fig. 1 four stationary nippers are represented arranged one above another, and through which the sliver is conducted to the rotary nippers.

The construction and arrangement of the two nipper-s G G are fully shown and described in my application for Letters Patent filed July 1.8, 1884, and of which the serial number is 188,044, and no further description thereof is necessary.

The fiber or sliver is delivered to the spindles and fliers of the two vertical tiers by two catenary series of upright bars or rods carrying gill-pins and moved by upper and lower chains working in horizontal planes. A portion*of one series of rods or bars and chains is shown in Fig. 1.

h designates the rods or bars, which are armed with series of pins If, corresponding to the number of spindles and fliers in the vertical tier; and h designates upper and lower chains, which are connected with and impart motion to the upright pin-bars h. The said upright pin-bars are guided at their upper and lower ends by tracks or ways 71/2 h and at that end of the lower track or way which is adjacent to the spindle-stand is a drop or de pressed portion, W, which permits the rods or bars 71. to fall, in order to withdraw the pins from the fiber and to enable them to sweep around under the stationary nippers G.

The chains of each series of pin-bars are operated by chain-wheels on an upright shaft, h, which is adjacent to the spindlestand,and one such shaft is shown in Fig. 1.

The upright shafts h, for driving the chains of both series of bars, are operated by bevelgearing h from a cross-shaft, h, and this crossshaft is operated by worm-gearing h from a shaft, h

The construction and arrangement of the two series of pin-bars, their chains and appurtenances, are fully described in my application hereinabove first referred to, Serial No. 137,907, and no further description thereof is necessary.

H designates a driving-shaft, to which motion is imparted, through a clutch, H, by a driving-belt, H, and from which motion is imparted by a belt, h, and pulleys h h to the shaft h The clutch H is shifted to stop and start the machine by a clutch-lever, i, fulcrumed at F to a bracket, i**, secured to a frame portion, F and the clutch -lever is moved to start the machine by a screw, i, having at the head an arm, t", which is connected by a rod, 6 with an arm, i, on arockshaft, i This rock-shaft i is to be shifted by treadles, as shown and described in my abovementioned application, Serial No. 137,907.

The fliers in the two groups are all operated by two belts, j y, from a pulley, 3*, on the driving-shaft H, as best shown in Fig. 2. One belt j passes around or encircles the pulleys c of the four fliers in the lower group, and another belt j passes around or encircles the pulleys 0 of the four fliers of the upper group, each belt also passing around the pulley f on the driving-shaft H.

By means of the two belts jj all the fliers are driven positively.

I'designates an upright shaft operated by worm-gearing h from the shaft h and J designates a traverse-screw, which is rotated continuously in one direction by bevel-gears is from the upright shaft I. The screw J has a compound thread, or two similar threads of reversed pitch, and upon it is fitted a carriage, L, which is provided with a swiveled nut or dog engaging with the screw-thread of the' screw J. Such a screw and nut are well known, and by the continuous rotation of the screw in one direction the carriageL is reciprocated to and fro. The carriage Lhas upwardly and downwardly extending arms m, forked to engage with annular grooves in the hubs of circular heads K, which are fitted to slide upon guide-rods Z, arranged centrally in the upper and lower groups of spindles, and with each reciprocating circular head K, engage the ringtravelers E of all the spindles and fliers in that group, and by such means the travelers are reciprocated to give them the proper traverse motion on the flier rods or stretchers A.

r The mechanism whereby the traverse-rings E of all the spindles and fliers are reciprocated is more fully shown and described in my above-mentioned application, Serial No. 137,- 908, and no further description thereof is here needed.

The spindlepulleys c of the two groups are operated by two slipping driving-belts, j, one belt encircling the pulleys 0 of the upper group, and a driving-pulley, j*, on the shaft H, and the other belt encircling the pulleys c of the lower group and the same drivingpulley j*. The two slipping driving-belts j also pass around or over and under tensionpulleys j j, which are pivoted or journaled to slides or; stock-pieces 1 capable of slidingvertically in guideways or channels j*, and

it will therefore be understood that by raising and lowering the tension-pulleys j j more or less tension will be produced in the belts j and the degree of their slip on the pulleys 7"* V and 0 will be regulated.

The arrangement of thebeltsj j and the pulleys around which they pass is best shown in Fig. 2.

Attached to the slides or blocks j*, which carry the tension-pulleys j j are cords or other flexible connections, r r, the course of which is best shown in Fig. 2. The cord 7' is carried directly upward over apulley, W, and attached to a movable frame, M, which is provided with an indicator scale or register, t; and the cord 7" is carried downward from the slidej of thelower tension-pulley, jiaround a pulley, a, thence upward and over a pulley, r*, and is also attached to the frame M. The cord r has a yoke, 1*, which embraces the shaft h", and its upwardly-extending portion is held behind guide-pulleys or guides 7", whereby it is deflectedout of the way of the belts j.

Near or in the frame F is an upright shaft, j, which receives motion by a worm or screw, j, and a worm-wheel, j, from the traversescrew J, and at the upper end of the shaftis a worm or screw, j, gearinginto a worm-whee], j, on a short horizontal shaft, j.

On the shaft 9' is a drum, j and coiled or wound thereon .is a cord or connection, j, which is attached to the indicator or index M, pivoted at j to the movable frame M, and also connected therewith by a spring, j. As the bobbins G are increased in size the cord j is wound upon the'drum j and draws the in- IIO dicator lWI M toward the left hand in Fig. 1, thereby increasing the tension of the slipping h driving-belts or drag-belts jj'.

The flexible connections 1" 1" and the mechanism hereinabove described for exerting a tension on the drag-belts jj. This may be done in any suitable manner; but Fig. l illustrates a mechanism which provides for freeing the shaft j from the gearing which rotates it in the operation of the machine and turning said shaft backward or in a reverse direction by hand.

Fig. 1* represents a sectional View, on a large scale,of the mechanism which connects the traverse-screw J, or, rather, the worm j thereon, with the shaftj the sectional View being in a plane transverse to the worm or screw j. The worm-wheel J is loose upon the lower end of the shaft j, and is connected therewith or locked thereto by a clutch-piece, j which engages by a pin and socket, 2,with the worm-wheelf, and is free to slide vertically on the shaft j, it being locked to the shaft by a spline or ieather, 8.

Z designates a short cross-shaft connected with the upright shaft j by bevel-wheels Z and capable of being turned by a hand-crank, Z, applied to its outer end,as shown in dotted lines. WVhcn the drum j is to be turned backward to lessen the tension on the dragbelts j, the clutch-piecej is raised until its pin 2 is disengaged from the worm-whcel j thereby freeing the shaft j" from said wheel, and said clutch-piece is held in an elevated position while the upright shaft is turned backward by the hand shaft and crank Z Z.

By showing the degree of tension on the drag-beltsj the indicator also shows the conditions of the bobbins as to fullness, and by glancing at the indicator the attendant can tell approximately how nearly the bobbins are full.
